Merging Partitions: AODV Each group leader periodically sends Group Hello Assume that two partitions exist with nodes P and Q as group leaders, and let P < Q Assume that node A is in the same partition as node P, and that node B is in the same partition as node Q Assume that a link forms between nodes A and B Q B A P 218
Merging Partitions: AODV Assume that node A receives Group Hello originated by node Q through its new neighbor B Node A asks exclusive permission from its leader P to merge the two trees using a special Route Request Node A sends a special Route Request to node Q Node Q then sends a Group Hello message (with a special flag) All tree nodes receiving this Group Hello record Q as the leader 219

Assume that node A receives Group Hello originated<br />

Node A asks exclusive permission from its leader P<br />
to merge the two trees using a special Route<br />
Request<br />
Node A sends a special Route Request to node Q<br />
Node Q then sends a Group Hello message (with a<br />
special flag)<br />
All tree nodes receiving this Group Hello record Q as<br />
